SPECIFICATION forming part Of LetterS Patent NO. 702,165, dated June 10, 1902.

Application filed August 8, 1901. Serial No` 71,326. (No model Improvement in Corn-Shock Compressors, of I which the following is a specification.

The invention relates to tackle-blocks of. that class more especially designed for useiu connection with means for compressing cornshocks or in connection with a wire-stretcher or for a light hoistg,` but the features thereof can be used with tackle-blocks for other purposes. j

The objects of the invention are to simplify and improve the construction and operation of the devices which enter into the construe-g tion of the tackle-block, more especially as regards the clamp for engaging the pulleyrope and the manner of actuating such clamp from the rope, to improvethe anchor orstay wire for supporting the tackle in its operative relation, and to improve in a general way the construction and operation of the devices*- which enter into the construction and operation of the tackle-block as a whole; and the invention consists in the features of construction and combination of parts hereinafter described and claimed; y

j In the drawings illustrating the invention, Figure 1 is a face view of the corn-shock compressor complete and in condition for use; Fig. 2, an edge elevation with the parts as in Fig. l, and Fig. 3 a face view with one side or face plate removed.

The block proper is formed of two plates of metal A and A', separated and secured a sufficient distance apart to leave a space between them for the location and operation of the pulley-wheel and the clamp for the rope. As shown, the `side or face platepA has cast therewith or suitably secured thereto lugs or projections a, a', and a2, one of which,a,forms a fixed jaw to coact with the movable jaw of the clamp, while the other two, a,`l and a2, have holes for the passage of screw-bolts 0,3, by

'means of which the face or side lplate A is attached to complete the block after the pulley and the clamp have been placed in position.

guide B, connected with the movable jaw C of theclamp by a-neck or stem b in the con- The rope passes through a socket orv struction shown. The socket or guide, with the movable jaw C of the clamp, are pivoted to the block by a pin or bolt c', so as to offset the point of pivot to one side of the center of the socket or guide, and thereby give ltheacting end or edge of the clamping-jawa |swing towardand from the fixed jaw a, by

which :the rope which passes between the actjingend or: edge ofthe movable jaw and the f face of the fixed jaw will be clamped and held, and inorder to insure a strong and rm bite on the rope, which will prevent the slipping thereof when clamped between the fixed and movable jaws, the movable jaw on its actingend has4 serrations or teeth c, which will press into the rope and eifectually prevent 'any slipping when the jawis swung into its clampingpOSitiOn. f VIVThe pulley-.wheel D, overwhich'the rope runs, is mounted on a stud d on the plate A,

whichenters a bearing d' in the side or face plate Af,so as to journal or mount the pul- 'leygwheel in the block, and the pulley-wheel has a grooved periphery, as usual, for retaining' the rope in place in traveling thereoveri A retaining or anchor rod E,having its body on a downward curve, is carried by the block,

land this wire has its end which is attached to the block turned to form a pivot e, which passes through ears e on the edges of the sidel snap through the hole fand holding thes'nap caught in the projection-'or ear bythe spring of the snap. The rope H passes over the puly ley-wheel on the side adjacent to the Wall or flange a? and thence around the edge of the wheel and through the opening between the fixed jaw and the movable jaw of the clamp and thence through the guide or socket B.

The clamp in operation is maintained clear and out of engagement with the rope by drawing in a straight line on the rope or in the direction opposite to the fixed jaw, which holds the serrated edge of the movable jaw away from the rope, and when it is desired to clamp the rope a slight pull thereon, so as to move the socket or guide in the direction away from the pivot of the movable jaw, forces the serrated edge of the jaw toward the fixed jaw, tightly clamping the rope between the two jaws, as the fixed jaw describes an arc of a circle sufficient to swing its acting edge in the direction of the fixed jaw to bite the rope. A slight pull on the rope in the direction to move the guide or socket away from the fixed jaw at once releases the clamping-jaw, allowing the rope to pass between it and the fixed jaw.

It will be seen that the construction of the pulley-block is exceedingly simple, employing but two side or face plates, one of' which has thereon flanges or walls to support the other, that the parts or elements composing the block as a whole are easily assembled, as all that is necessary is to set the pulley-wheel onto the stud of the side or face plate having the flanges or walls and to set the clampingjaw into position on the same plate and then placing the removable side or face plate into position, passing the pivot-bolt for the clamping-jaw through both plates and the jaw and passing the clamping screws or bolts th rough the plates and attaching the nuts, if bolts are used, which completes the assembling and uniting of the block as a whole, with the pulley-wheel journaled between the two plates and the clamping-jaw pivoted between them, the fixed jaw and the acting end of the clamping-jaw having such relation one to the other as to permit the free passage of the rope beneath them when drawn straight or away from the fixed jaw without hindrance, and at the same time the clamping-jaw is so pivoted that a slight pull of the rope against the socket or guide in the direction away from the pivot of the jaw at once forces the acting edge of the jaw toward the fixed jaw, firmly clamping the rope between the jaws. The retaining or anchoring wire is pivoted to the block at one edge and extends across the face of the block, so as to be in easy position for handling and use, and the curvature of the wire is one which permits of its ready insertion and withdrawal in use. The tackle-block as a whole, it will be seen, is exceedingly simple in construction, easily applied for use, and has the clamping-rope under direct and positive action from the pulley of the rope, which are desirable advantages in the operation of tackle-blocks.

The pivotal point of the movable jaw is off side and the socket or guide for the rope has such relation to the pivot and the acting end or edge of the jaw as to hold the jaw clear of the rope in pulling or drawing on the free end to tighten or draw the rope taut, and with the release of the pull or draw the strain on the attached end of the rope will act and pull the socket or guide over, forcing the movable jaw against therope for tho socket or guide and the jaw to operate and hold the rope firmly and securely between the jaws. The jaws will be thus held so long as the strain continues, and the greater the strain the greater the force exerted to hold the movable jaw closed on the rope.

The use of the block and the draw-rope connected therewith as a compress for drawing together a shock of corn and other like purposes, in which after the shock or bundle has been compressed ithas to be secured byatying-cord, requires that the cord should bein position to be readily passed around the shock orbundle, and for this purpose it is desirable to have the tying-cord carried around with the compressing-rope. This result is attained with my improvement in tackle-blocks by forming an eye or loop E in the retaining or anchoring wire adjacent to the point where such wire is pivoted to the head of the block for the tyingcord I to be threaded or passed through the eye and its free end caught beneath aspring g, attached to the snap-hook, so that with the encircling of the shock or bundle by the `compressing-rope and attaching the snaphook to the tackle-block the tying-cord will be carried around with the compressing-rope and be in position for tying without the necessity of making a second triparound the shock of corn or other article in order to get the tying cord or twine around the shock or bundle.

In use the anchor E is run into the shock to be compressed and the block brought down in edgewise transverse relation to the shock. The compressing-rope and the tying-cord are then simultaneously carried around the shock, as above described, and the compressing-rope is pulled tight. The anchor E serves to hold the block into firm contact with the shock during the compressing and tying operation and to prevent it from being carried around the shock by the tension of the rope as it is drawn tight, while the downwardcurvature of the anchor, although more firmly anchoring the block during the compressing operation, permits of its ready withdrawal thereafter.
